Population Above the EPA Outdoor Threshold
The EPA's 55 dBA outdoor reference level is a common benchmark for residential noise exposure, especially for activity interference, annoyance, and long-term community noise concerns. About 1,061 Moline Acres residents, or 50.9%, live above that level. By land area, 58.0% of Moline Acres is above 55 dBA.
Average noise levels for Moline Acres residents, grouped by direction from the center of Moline Acres. Western Moline Acres carries the highest population-weighted average; Eastern Moline Acres carries the lowest. Just 29% of residents in Eastern Moline Acres live in blocks above the EPA's 55 dBA threshold, about half the share in Western Moline Acres.

QuietLoud
Western Moline Acres sounds about 26% louder than Eastern Moline Acres to the human ear, a 3.3 dBA gap. Every 10 dBA roughly doubles perceived loudness. Within any of these directions, two homes a quarter mile apart can still differ by 10 or more dBA depending on how close they sit to a major highway.
How far back from Chambers Rd do you need to be?
Chambers Rd produces an estimated 65 dBA at its loudest centerline points. Noise drops logarithmically with distance, with the exact rate depending on what's between you and the road. Tree cover, walls, terrain, and pavement type all matter. At roughly a quarter mile back, traffic fades into the noise level of a soft rainfall.

Calculated from the model's calibrated attenuation formula. About 33% of Moline Acres sits under tree canopy (about average for cities) and roughly 34% is impervious surface like pavement and rooftops. Both are folded into the per-place decay rate above. Heavier canopy pulls noise down faster with distance; impervious surfaces slow the drop.

Airport Noise
St Louis Lambert International (STL) sits west of Moline Acres. The U.S. Department of Transportation models aviation noise around this airport from federal traffic data, and the model uses those federal measurements rather than synthetic predictions.
Blocks under the approach and departure paths carry combined road-plus-aviation noise, with some exceeding 65 dBA on the map's Overall layer. Blocks on the opposite side of Moline Acres, particularly to the east, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Moline Acres
The bar chart below shows the share of Moline Acres residents in each noise band. About 21% of residents live below the EPA's 55 dBA threshold, and roughly 11% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Moline Acres Compares
Moline Acres sits at the quieter end of the spectrum. Below: how Moline Acres's average outdoor noise and share of residents above the EPA threshold compare with Pine Lawn, Bel-Ridge, Riverview, and Pagedale.
Average noise level (dBA)
Moline Acres's 56.3 dBA pop-weighted average is at the quieter end of the spectrum. Missouri as a whole averages 53.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Moline Acres because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 50.9% of Moline Acres residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's in the middle of its peer group. Measured by land area instead, 58.0% of Moline Acres's footprint sits above 55 dBA, against a Missouri average of 32.5% and a national average of 28.1%.
What This Means if You're Moving to Moline Acres
Distance from highways matters more than the neighborhood name. Two homes in the same zip code can differ by 20 dBA if one sits 100 meters from Chambers Rd and the other 500 meters away. The model captures this at 100-meter resolution, so noise exposure changes block by block.
Tree canopy can help reduce modeled noise exposure. Roughly 33% of Moline Acres is under tree cover (about average for cities), and the dominant land cover is low-intensity developed land. Both are measured from federal USDA Forest Service and USGS satellite imagery at 30-meter resolution. Streets with 60% or higher canopy show 3 to 5 dBA lower noise than comparable streets with bare ground or pavement, which is why the per-place decay rate above already accounts for it.
Airport noise is directional. St Louis Lambert International's approach paths concentrate aviation noise to the west. Neighborhoods to the east of downtown show no measurable contribution from the airport.
Sources & Methodology
The BestNeighborhood noise model is calibrated against nearly one million federal ground-truth measurements across four states. Road noise is computed from segment-level federal traffic data and propagated outward using physics-based acoustic decay, with attenuation rates that depend on the surrounding land cover.
All inputs are published federal datasets. Block-level noise is computed by combining road, rail, and aviation sound sources in the energy domain, the same physics used in professional environmental noise assessments. Read the full methodology.
